A drag bar or beam 11 is provided at its 1 frontzend with a pivot-bracket 1?,Whereby. the beam can be attached 'to'the frame of a seeding-machine. A bearing-bracket 13 is rigidly secured to beam 11 by bolts or rivets 14 and forms the bearing or support in which aconeavo-convex disk 15 is journalfed.

disk against lateral and vertical play. The

journal for the disk comprises a stud 20', having an enlarged portion or flange 21 fitting in recess 17 of hanger 13 and having a cylindrical central portion 21, extended through and fitting in the opening within rib 18, and a poly onal or non-cireular end portion 22, extends through a eorres ond'inglyshaped opening 24 in a spacing-col ar 23 and a similar opening 25 in disk 15. The polygonal end of stud fitting in said openings in the collar and disk secures the stud and collar to revolve with the disk. A tie-bolt26 extends centrally through the stud and disk and clamps these parts together. Preferably a washer 27 is interposed between the head of bolt 26 and the convex face of the-disk, and a lock-nut 28 at the inner end of said bolt lies I .Within a pocket or recess 29 in stud 20. (ollar 23 is clamped betwcen'the concave face of the disk and a shoulder 30 of stud 21), which also fixes the relation of collar, so the bearingsurfaces of the collar and stud will be free to revolve in the-bearing. Collar 23 fits with in that portion of the bearing adjacent the con-- cave face of the disk and is formed with a rib 31, fitting into a groove 32 in bearing 13, and this construction effectively excludes dust from the hearing-sr'lrl'accs, because the dust cannot pass along the sinuous surfaces.

Bearin -bracket 13 has formed therein a upper end of duct 34 is closed by a cap 36,

etween the. drag-bar and the side of'hanger 13 to prevent escape of the lubricant. A plate 40, secured to hanger 13 by rivetsor olts 40, forms a closure, which prevents'em' try of dust at one side of the bearing. A strip of packing or gasket-41 between plate 39 and bearing 13 prevents esca e of oil from the hearing, so the lubricant wi I be retained produced.

in the bearing.

A seed-delivery conduit or boot 45 issus tained adjacent the rear of the disk and atthe convex side thereof by a recessed lug 46, integrally formed with the boot and secured to the rear end of the drag-bar by a bolt 47..

As well understood in the art, the disk is set at an angle with respect to the line of draft to 0 en a furrow of the desired depth and width. T IGYIOWGI terminal of the boot is positioned to deliver seed into the lowest part or center of the furrow. A blade, preferably of polished steel, comprises an extension 48, secured to the boot by rivets 49, and a scraper 50, having its lower edge sharpened and bent into contact with the convex face of the disk. Extension 48 forms the outer wall of that portion of the boot which travels in the furrow and against which the loose soil falls and being formed of polished steel easily passes through the furrow and soil and deflects the SOll away from the boot. In other words, the extension constitutes a scouring-blade,

which effectively prevents the soil from ad" hering to the boot. Scraper 50 removes the lower portion orwall of the boot has its outer side cut away, as at 51, or openly formed, and blade 48 forms theoutcr side of said'poe tion of the boot, which construct ion provides a boot the lower end whereof scours in the soil and .is made narrow so it will travel nicely in the furrow. The lower portion of the seedwonduit, which is formed by the boot and blade =18, is tapered, (see Fig. 3,) so it will easily travel in the furrow, and rivets 49 are preferably loea'x-ted some distance above the l m ttern 1inal to avoid extending the rivets through the thinnest portion of the boot.

The invention possesses several important advantages over prior constructions. 'lhe scouring-blade at the foot o'fthe boot effect-- 'ively prevents the 301i from adhering to the boot. The scraper for the convex side of the disk and the scouring-blade being formed of a single plate or strip of metal can be cheaply The compact construction and the arrangement of the bearing-disk and sus- The taining-bar, hereinbefore set forth, leave in creased clearance-spaces between the disks of a gang and avoid accumulation of trash between drills of a gang. Furthermore, these wide clearance-spaces make it possible in practice to set the disks in close relation, to

open furrows in closer proximity than has heretofore been customary and 'still avoid such accumulation, whichresultant advantage is an important one, because in some sections of the country closer arrangement of plant rows is desired which was not possiblein constructions in which there was less clear- 'ance between the disk and disk-support of one furrow-opener and the next in the ang.

The improved construction of diskcar ing is such that dust is excluded from the bearingsurfaces and the lubricant is retained in the bearing. The construction-of the bearing, with its ribbed spacing-collar and correspondingly-shaped recess of the bracket, make it possible to position the disk into close proximity to the bearing and sustaining bar. By employing a drag-bar, which extends to the rear of the disk and is there secured to the boot, and a separate bearin bracket for the disk an improved and simp e construction is ,provided, in which the bearing is located on the concave face and the boot on the convex'face of the disk, which arrangenient in practice is referred, because the bearin is kept clear of oose soil. vantage 0 cm loying an open oil-recess in the side of the bracket is that a recess of the desired shape can be cast in the bracket.

The several features of the invention are not to be understood as restricted to the precise details set forth, because these may be varied by the skilled mechanic without departing from the spirit of the invention.
